A suggestion to create a busbar.
See discussion here:

A long male header pin can change the gender of the Dupont connector.
If +5v and GND are both needed, use red and black wires.
Red would go the even number pins.
Black would go to odd number pins.
A two pin header would then be the supply connector.
